Why Your Check Engine Light Is On

Few dashboard warnings cause more stress than the check engine light. While it can indicate something minor, it can also signal a serious problem that should be diagnosed as soon as possible.

At Shoreline Automotive in Porters Lake, we provide diagnostic services for drivers from Musquodoboit Harbour, Head of Jeddore, and Lake Echo.

Common Reasons for a Check Engine Light

Here are some of the most common causes.

Loose Gas Cap

One of the simplest causes is a loose or damaged gas cap, which can affect fuel system pressure.

Oxygen Sensor Failure

The oxygen sensor measures the amount of oxygen in exhaust gases and helps regulate fuel efficiency.

Faulty Spark Plugs

Worn spark plugs can cause engine misfires and reduced performance.

Catalytic Converter Issues

The catalytic converter reduces harmful emissions. If it fails, your vehicle may lose power and fuel efficiency.

Mass Air Flow Sensor Problems

This sensor measures how much air enters the engine and helps determine fuel delivery.

Why You Shouldn't Ignore It

Ignoring a check engine light can lead to:

• Reduced fuel efficiency

• Increased emissions

• Expensive engine repairs

A quick diagnostic test can identify the issue before it becomes serious.
